NHTSA Complaint #10374694 — 2009 CHEVROLET AVEO

MY 2009 CHEVROLET HAS HAD SERIOUS STALLING OR NON RESPONSIVE ACCELERATION FOR 6 MONTHS NOW. ON A REGULAR BASIS THE CAR WILL LOSE POWER TO THE ENGINE; WHEN STEPPING ON THE ACCELERATOR PEDAL. THE CAR ACTS LIKE THERE IS NO SIGNALS FROM THE ACCELERATOR PEDAL TO THE THROTTLE ASSEMBLY. THERE ARE DAYS WHEN IT DOES NOTHING AT ALL. THERE ARE TIMES WHEN IT HAPPENS THEN THE ENGINE WILL JUST SEEM TO RETURN TO NORMAL, THEN OUT OF THE BLUE THE ENGINE WILL LOSE POWER AGAIN. THERE ARE NEVER ANY WARNINGS OR CHECK ENGINE LIGHTS. NONE HAVE EVER COME ON. WE HAVE TAKEN THE CAR TO 3 DIFFERENT CHEVROLET DEALERSHIPS; AND TO ONE INDEPENDENT GARAGE; WHO DID HAVE THE PROBLEM HAPPEN ONCE WHILE I WAS DRIVING WITH THE OWNER, BUT THE OTC GENISIS DEVICE COULD NOT IDENTIFY WHAT WAS HAPPENING, IT JUST RECORDED THE HISTORY OF THE EVENT. NONE OF THE CHEVROLET DEALERS COULD GET IT TO DUPLICATE OR FIND ANY CODES IN THE 10 DAYS THEY HAD THE CAR. THE PROBLEM SEEMS TO BE GETTING WORSE. I HAVE BEEN TAKING VIDEOS WITH MY HTC DROID WHEN THE CAR IS HAVING ITS PROBLEM (FOR ALL THE GOOD THAT WILL DO). IT IS LIKE KEEPING A JOURNAL. I SHOW THE RPM SPIKES AND DROPS; THE SUDDEN DECELERATION AND THE ?NO RESPONSE WHEN THE GAS PEDDLE IS PUSHED. THE PROBLEM HAS OCCURRED AT ALL SPEEDS, INCLUDING WHEN ON THE FREEWAY. WE HAVE ALREADY SPENT OVER $600 ON VARIOUS (SO CALLED FIXES); INCLUDING A COMPLETE FUEL SYSTEM CLEANING (INCLUDING THE THROTTLE BODY CLEANING) NONE HAVE EVER HELPED. I WAS TOLD BY A CHEVROLET DEALER IT WAS A BAD O2 SENSOR (BUT NO CHECK ENGINE LIGHT HAD EVER CAME ON). O2 SENSORS ALWAYS CAUSE A CHECK ENGINE LIGHT TO COME ON. I THINK IT MAY BE THE ENTIRE ECU COMPUTER; BUT NO DEALER WANTS TO ADMIT THAT. I WAS TOLD BY THE DEALER TODAY 01/04/2011; THERE IS NOTHING MORE THEY WILL DO; BECAUSE WE HAVE TOO MUCH NEGITIVE EQUITY. THEY WILL NOT DO A BUY BACK. THEY HAVE WASHED THEIR HANDS OF THE ISSUE. TO BAD THERE IS NO USED CAR LEMON LAW. 4 REPAIR ATTEMPTS AND THE PROBLEM IS EVEN WORSE. *TR
